Senior Process Integration Engineer

About OLIXAI is growing faster than any technology in history and the explosion in demand has created a massive infrastructure gap; we can no longer build chips or power stations fast enough to keep up. The industry is still leaning on a ten-year-old hardware blueprint that has reached its limit. A new paradigm that is faster and more efficient will be the biggest economic opportunity of the next century and create the most important company of the next decade. OLIX is building this next paradigm; the Optical Tensor Processing Unit (OTPU) achieves performance and energy efficiency that is impossible to match from existing chips.

The Role

We are looking for a Senior Process Integration Engineer to design and implement bespoke fabrication flows for advanced micro-optical and MEMS-based devices. You will bridge the gap between R&D concepts and manufacturable reality, building, iterating, and qualifying custom process sequences that underpin our next-generation hardware. This role combines hands-on technical depth with strategic process integration oversight. You will spend time both in the cleanroom developing new flows and outside it, collaborating with partner fabs, R&D institutes, and equipment suppliers to push process capability forward.

Responsibilities

• Custom process flow development - architect, prototype, and refine fabrication flows across silicon, glass, or compound substrates for MEMS and optical structures.
• Rapid prototyping & iteration - drive fast cycles from CAD to measured die, identifying and optimising key process levers.
• Process definition & scale-up - document mask sets, material stacks, and dependencies; mature experimental flows into repeatable, pilot-ready documentation.
• External collaboration - work directly with R&D partners, universities, and equipment manufacturers to qualify new process steps, tools, and materials.
• Hands-on execution - operate and troubleshoot core process tools (lithography, deposition, etch, bonding) during development and transfer phases.
• Strategic oversight - guide internal technicians and external partners, ensuring process discipline, yield learning, and structured design feedback.
• Data-driven optimisation - use DOE/SPC and metrology data to accelerate convergence and maintain process control.
• Knowledge capture & review - maintain detailed process documentation; run internal reviews and FMEA sessions.

Skills & Experience

• 5-15 years of experience in MEMS or advanced micro-fabrication, with deep process integration expertise.
• Proven record creating or modifying complete process flows for novel MEMS or micro-optical devices.
• Strong background in at least three of: photolithography, DRIE/RIE, thin-film deposition (PVD/ALD), wafer bonding, or wet etch.
• Comfortable switching between hands-on tool-level work and high-level process architecture and partner coordination.
• Experienced collaborating with external fabs, R&D consortia, or tool vendors to develop or transfer new capabilities.
• Proficient in DOE/SPC tools (JMP, Python, etc.) and disciplined process documentation.
• B.Eng./M.Sc./Ph.D. in Materials Science, Electrical/Mechanical Engineering, Physics, or related field.
• Excellent communicator; thrives in fast-moving, interdisciplinary environments.
• Familiarity with wafer-level packaging or flip-chip integration for MEMS or optical devices.
• Experience transferring R&D processes to external pilot or production environments.
• Working knowledge of simulation and characterisation (FEM, profilometry, interferometry, L-I-V, or spectral testing).

Compensation & Equity

• Competitive Salary: £82,000-£119,000, commensurate with your experience, skills, and location.
• Equity & Ownership: Meaningful stock options. You are not just joining the mission; you are owning a piece of it.
• Proximity Bonus: We value your time. To minimise your commute and maximise your life, we offer a £24k annual Living-Local Bonus if your residence is within 20 minutes of the office.

Health & Wellbeing

• Premium Healthcare: Comprehensive BUPA medical and dental cover, including Medical History Disregarded (MHD), for complete peace of mind.
• Time Off: 25 days of annual leave, plus all UK bank holidays.

The Workspace & Tech

• Elite Hardware: M4 Macs come as standard, with M4 Pro upgrades for our engineering team. We will provide whatever you need to do your best work.
• Optimal Environment: High-spec noise-cancelling headphones and a fully ergonomic workstation designed for deep focus.
• Rapid Prototyping: Access to our high-performance 3D printing lab for work, experimentation, and personal creative projects.

Life at the Office

• Chef-prepared meals: if you need to work late.
• Caffeine on Us: We have got you covered with a tab at our favourite local coffee shop.

Relocation & Global Mobility

• Visa Sponsorship: We hire the best in the world. We offer full UK and international visa sponsorship.
• Seamless Relocation: Whether you are moving across the country or across the globe, our dedicated relocation partner provides funding and concierge support to get you settled.

Due to U.S. export control regulations, candidates' eligibility to work at OLIX depends on their most recent citizenship or permanent residency status. We are generally unable to consider applicants whose most recent citizenship or permanent residence is in certain restricted countries (currently including Iran, North Korea, Syria, Cuba, Russia, Belarus, China, Hong Kong, Macau, and Venezuela). Applicants who have subsequently obtained citizenship or permanent residency in another country not subject to these restrictions may still be eligible.
